^ Application tiled February 15. 1911. Selinl No. 608,768.

lie it known that l, VHJJAM l?. DUNN, n citizen oit' tliedi'nited States, residing in the ('itv :ind oonnty of Philadelphia, Stute of lehnsvlrnnia, have iilvented n new :ind nso fnl Linking' Device t'or (fors :ind the Lilo, of which the following` is i1` sperillenlion.;

This invention relates to looking devices for doors of railway cnrs ond more pnr-y tlcnlnrlv to freight enr doors :ind hns for :in ohjoet tio provide. means to look the doors of a enr in n` secure und eli'ective rnun'ner.

l't has for n further ohieet to provide :i signal device, cooper-:dii y positioned wlth respect to said lfiwlrino' ineens, Whereliiy should any of the doors be unlocked the trainieren inoy he :ipprised oi' the toot.

,lt further oonsiss of other novel features of construction, :all as will be hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in the accompanying drawings one torni thereof which is ot pres ont preferred by me, since tho saine has been. vfound in inuetieo to give satisfactory and reliable results, although it is to bo linden stood that the vorions instrnmentalities of which my invention consists een he variously wronged :ind organized and that my .invenn lion is ,not limited to the precise arrangenwnt and organization of these instrumen tzilities :is herein shown and described.

Figure 'l represents :i section of n portion of n vor showing a looking mechanism ein- Fig. 2 reliiresents a section on line :if---w, Fig. 1. F ig. represents n portion of the top of si car showing o. detail of construction. Iiigs. 4, 5 und 6 represent respectively, modifications of the operatingr mechanism oi the locking device. Fig. 7 represents u section on line y-y, Fig. 6,

Similar numerals of reference indicate oorresptmdng;f parts in the figures.

Referring to the drawings :"1 designates in the present instance the top of a freight 0:11', of which 2 represents the sidesnnd 3 the nbnnl side doors slidingly mounted in the guides Il. as will he apparent.

designates the holtens of the doors 3, oooh of which marries infjthe present instance, n bushing set therein rind forming n socket with which the bolts 7 ot the locking device are :ulapled to coiierute. lfhese bolts 7 nre properly guided with respect to these bushings F5 by means of the guide brackets 8 prefrrnhli' sof-nred :idjnvont tno doors und cor- Verily loi-:ded with respect to the said hushmes.

f) designates; :1 suitable guide brut-kot, for the bolts 7, secured hy fasteningr devices l0 lo the top l of the our. Suitable openings I l ore provided in tho brzwket i) to guide the bolts 7 und permit free sliding movement for proper operation of the several ports.

12 desigiintes :is here Shown a :spring ineinbrr secured :it opposite ends t0 the respontiveholts 7. Suitable securing devices 13 :ire utilized lo connectthe member l2 to the bolts 7.

14 designates un arm having :i Clip 15 prefernblg,Y secured thereto by e. pin 16 or the. like nfld positioned to provide n suitable space to reireive the spring` member l2 to the said arm '14. It will be noted that the orni 14 is preleiuhiy, of sullioient length to project exterior oi' the top l. when the locking bolts 7 are in released position. An opening' 1T is of course located in the top 1A ,in :llinenint with the arm 14 in order to permit proper operation thereof.

18. designates a guide block secured by studs 19 or the like to the car frame 20, both the bleek 18 and frame 20 being apertnred for the passa-ige of the arm 14.

2l designates z suitable closure removably mounted in the opening,r 17, in the present instance having; :i hinge 22. This construction allows :1f-.cess to the arm 14 for operatingr purposes sind also provides no obst-rnction on the top of the cnr.

Attention is directed to the fact that the lock operating mechanism is positioned beneath the running boord 23 which is also provided with a hinged closure 24. This closure 24 serves ns a signal or indicating device by 'which the position of the looking; devices nmy be determined, that is to soy by :i ,glance along the top of the our anyone muy determine whether or not any of the closures on the several cnrs :1re open.

F25 designates i1 plurality of .staples adapt-- ed to roof-ire the usual our .sealing devire 2F hy which the smiling of the oar is effected to prevont tznrniering with the looks.

ln Fig. l il inodilii'ntion of the look open :ding: merlmnisin consists :is here shown, ot :i .spindle 27 having a pinion 28 for en- :i; 'eriit\li'ly 'with the segment ,gears 25) mounted respwively on links 30. These links 30 .have o. pivotal connection 31 with the respective bolts .7.

In Fig. 5 another embodiment is shown wherein links 32 form a direct connection between the bolts 7 and an arm 33 which latter corresponds to the arm 14 heretofore described. A spring 34- encircles a potton of this arm 33 and bears at one end against the bracket 9, while its opposite end presses directly against the links 32 and-causes the 4releasing of the bolts 7 as soon as the seal 26 In unlocked position the arts assume the osition shown in Fig. 1 t e arm 14 being hield up by the spring 12 and retainin the closures 21 and 24 open.A The latter 24 eing located in the runnin board forms a signal which may be rea ily seen by a glance along the top of the car. This is an irnportant feature since the Caboose windows are alined with the top of the cars so that the top of the entire train is in view.

The locking of the doors is effected by ressing the arm -14 downwardly to drive liome the bolts 7 after which the closure 21 is dro )pcd and sealed and the closure 24 lowere as shown in Fi 2. The parts are thus firml and securel dockedl together and can only lie released y breaking the seal 2G. Should anyone tamper with the device and break' the seal the sprin release immediately-opens the closures an gives a visible signal which can be seen from the caboose.

It will now be apparent that I have devised a complete unitary structure, simple in construction, effective in operation and :by

4#which the doors of a oar may be securely ifastened and further any tampering with or unlocking of the 4same will cause an indicae tor to be displayed warning the trainmen.

It will now be 'apparent that I have devised a novel and). useful construction of e lookin device for cars and the like which embodies' 'the features of advantage enumerzited as desirable in the statement of the invention and the above description, and while I have in the 'present instance, shown and described a preferred embodiment theref which has -been found in practice to give combination with a cur top, a closure there actuated. by said oliwraliin;l mechanism und means to release said boltffwhen said signal moans .is free to operaie.

2. VIn a device of the oliaracter stated, in? coinbimlion with a car top, of a olf# c .l therein, car doors provided with soclzol-V 'is and kicking devices consisting ot an. :irn mounted beneath said closure, a. plurality of bolts cured to said arm and adopted to engage said sockets and means to release said bolts.

3. In n device of the character stated, the combination with a car top, of a closure therein, car doors provided with sockets and locking devices' consisting of an arniinount ed beneath said closure, a plurality of bolts secured to said armand adapted to engage said sockets and a spring for releasing said bolts. i

.4. In a device of the character stated, the

in, a runnin board on said top a elo we therein aline with said top closure, ot far doors provided with sockets. and locking devices consisting of an arm lnountedbenenth said closures, a plurality of bolts secured 'to said'ai'm and adapted to engage said' sockets and a spring for releasing said bolts.

5; In a device of thecharacter stated, the combination with a car -topz a closure there in, a runnin board on sld top a closure therein aline with said top closure, ofcar doors provided with' sockets and lookin g de vices consist-ing of 'anerm mounted beneath- 1mi Y said'closures and adapted to project tliroiigh said top in unlocked position', a plurality of bolts secured to said arm and adapted to enga e said sockets and means for releasing sai bolts. i y
